guys cie dont expect the candidates to be engineers and wknow what is used to reinforce concrete... i think its just common sense....they mentioned that the expansion of steel is the same as concrete, and aluminium isnt, so if u use aluminium it would expand at a different rate than concrete, and it would cause problemes to the structure.and plus... its known that steel is used to reinforce concrete

since 21 hours have past, i'm sure by know everyone on the planet have taken the testso how was itBy the way what was the mass and the fraction on the energy question
i did evrythng as u guys dd and in da first q i used da alpha emitter and i said 2 put an alpha emitter and put infront of it a paper and behind it a detector and then i said depending on da no of alpha rays able to penetrate da paper and detected by da detector the thickness can b determined if too many rays pass dat means its very thin if nothing passed that means its very thick....is it right? did any1 do it like me ?
GET OVR THE PPR PPL!!!!!THE MORE U DISCUSS,THE MORE I KNO I M GETTING BELOW C!!!!:(
Erm, guys how are you preparing, like, COMPLETELY for Paper 1?... So far, I only practiced many papers and I know now that I have to sleep early on the exam night.
